After adjusting for the systematic difference in BP between the two methods calculated in the validation study (3.9 mmHg for systolic and 3.0 mmHg for diastolic), morning and daytime (average of morning and evening) HBP were significantly lower than morning (average of 2 h after waking) and daytime (average of being awake) ABP, respectively. No significant difference was found in nocturnal BP between HBP and ABP monitoring regardless of the quality of sleep during nocturnal HBP measurement. Agreement between HBP and ABP in the detection of non-dippers was low mainly due to the difference in daytime BP values. Conclusion: HBP monitoring may be a reliable alternative to ABP for the assessment of nocturnal BP.
